多层靶不同运动状态对高速球形弹侵彻的影响

The Impact of Multilayer Target's Different Motion on High-speed Spherical Projectile Penetration

为了研究多层靶运动状态对高速球形弹侵彻性能的影响,应用ANSYS/LS-DYNA软件,通过数值模拟建立了高速球形弹对多层薄靶板的侵彻模型;对不同运动状态下球形弹多角度侵彻多层薄靶板与静态单层同质量薄靶板的干扰效果进行了对比;得出靶板在静止时,等厚多层靶比单层靶的防护效果要好;水平负方向运动时的防护效果会低于正向运动,且随着入射角的增大而增大;当爆炸飞板法向高速飞行时,对球形弹的防御效果随倾角的不同呈现不同的规律。

In order to study the effect of motion of multi-layer target on penetration of high-speed spherical projectile, the model of high- speed spherical projectile penetrating thin multi-layer target board was numerically simulated by the software ANSYS/LS-DYNA. Compari- son between dynamic penetration of thin multilayer targets in different motion state and static penetration of one layer thin target with the same mass was made. When the target is stationary, the pretective effect of the uniform thickness is better than that of the single-target. The protective effect is lower when moving in the horizontal negative direction than when in the forward direction and increases with increas- ing angle of incidence. When blasting plate moves normally in high speed, the defense on armor-piercing effect with different inclination shows a different rule.
